Influence of the concentration of suspended substances on the permeability of porous reservoirs at mechanical colmatation

The article discusses the effect of the concentration of suspended solids on the permeability of porous reservoirs during mechanical colmatation in the areas of underground leaching and the development of methods for preventing mechanical colmatation of reservoirs, mainly due to the introduction of suspended solids contained in injected solutions into productive horizons. The degree of clogging of porous reservoirs was determined, which was assessed not only by changing the rock filtration rate when filtering liquid containing suspended solids, but also by changing the particle size distribution of the filter media in the columns.
